Insights

Financial Analyst

TL;DR: A small insider purchase: director acquired 26 shares at $33.13, leaving total holdings of 3,733.1224 shares.

The transaction is a routine, non-derivative acquisition executed via open-market purchase and supplemented by dividend reinvestment. The size of the purchase—26 shares—is immaterial to company capitalization and unlikely to affect valuation metrics. It does, however, confirm continued insider participation in shareholding.

Corporate Governance Expert

TL;DR: Disclosure is timely and complete for a single reporting person; transaction appears compliant with Form 4 requirements.

The Form 4 identifies the reporting person as a director, specifies transaction date and price, and includes an explanatory remark about dividend reinvestment. The filing was signed by power of attorney, which is explicitly shown. No omissions or ambiguous entries are apparent within the disclosed fields.
